Phys.org / Much of Earth's 'space dust' may come from unidentified near-Earth asteroids

Like a shelf in an old house, the Earth collects a lot of dust from its surroundings. This "space dust" is mostly made up of micrometeorites that survive atmospheric entry and provides researchers with a cheap and easy way ...
